I have the report of John Smith's death in the Fraserburgh Herald & Northern Counties Advertiser May 28, 1907 which reads "Groom Killed by Stallion" John Smith, groom and feuer, 136 High St New Pitsligo, received fatal injuries at Commonty Farm New Deer, on Tuesday. Smith who was in charge of an entire horse was taking the animal from the stable, when it pushed him over and put a hind hoof on his chest, causing such serious injury (I guess so!) that he lived only for half an hour afterwards." coroners report..."injuries sustained by being accidentally knocked down and trampled upon by an entire horse under his charge; per verdict of jury"
Not being knowledgeable on horse breeds, I can't tell if this horse is a Shire .
